Absolutely right. If you solder them with the valve open, they won't seal
tight when closed.

Quite often I see a question about
soldering a ball valve. Without question
the ideal way is to use male adapters, and
use a threaded valve. But this isn't
always easy to do. I actually wrote, and
asked Nibco, one of the larger makers of
ball valves, the proper way to solder a
copper ball valve. I will attach their
letter, but it states to close the valve, and
then wrap a cool rag around the body of
the valve, and solder.


I've soldered thousands of them open and closed never use a wet rag around
them unless I'm brazing "close" to them The biggest problem I've
encountered is lose packing nuts causing a drip. One time the quality of the
valves was so bad we tightened all the packing before installing them.
